Any member of one's chosen gender that makes it into that piece of furniture ordinarily used for sleeping (or, alternately BUMPIN' AND LOVIN' IN THE BED). A bed-buddy's purpose is usually sexual in nature, although s/he may also be a cuddle provider.

"HEE HEE PET PET" is the near-incoherent inner babble of a person who is engaging in pleasurable physical activity (petting) with one of their chosen gender, more than likely for the first time in a long time; this can refer not only to the exclamation but to the activity itself.
